Figure 4

Effects of the initial induction biomass on the HCDF.

(a) Cell density profiles (DCW). (b) Volumetric enzyme activity profiles (U/L). (c) Biomass enzyme activity profiles (U/g). Data are means ± SD of three parallel measurements (*P < 0.05, **P < 0.01, ***P < 0.001). Note, the initial induction biomasses (g/L) were: 50 (filled cycle), 75 (open cycle), 100 (filled diamond) and 140 (filled square), respectively.
